This looks like a snippet of an autoconf AC_CHECK_LIB (or AC_CHECK_FUNCTION) test. Such tests don't work with 32-bit Win32 APIs -- on either Cygwin or MinGW -- because they don't take stdcall into account. You'll need to modify the test to work around that.
Also, if you're using Cygwin, do you *really* want to be using Win32 OpenGL and not X11?
